Recently I updated my system to Win 10 Creators update 1703.
After the update has been applied, all HMG compilations (3.4.2., 3.4.3 and 3.4.4. EXE-files) produced one and the same error when trying to open an Excel file with the standard (and working with no problems till now) statement of the type for example:
oExcel:Workbooks:Open(fPATH + fXLSXTemplate, .Y.)

All Excel trusted settings have been disabled, so this seems to be not an Excel security issue (conflict).

I also downloaded and ran MS Office Configuration Analyzer Tool but no errors and reccomendations have been given.

And this is one of all HMG-error messages (all are identical):
Date:17/05/2017 Time: 21:53:09
Error WINOLE/1007 Argument error: OPEN (DOS Error -2147467259)
Called from TOLEAUTO:OPEN(0)
Called from PRNFAKTURAKABFN(581)
Called from GETK_RECORD(76)
Called from (b)MAIN(146)

Called from EVENTS(1756)
Called from DOMESSAGELOOP(0)
Called from _ACTIVATEWINDOW(5717)
Called from DOMETHOD(9003)
Called from MAIN(297)

Has anybody encountered a similar problem with any Office component? My Office is ver. 2016.

Regards,
Marin

P.S. As of 21.05.2017: The problem has been solved. Due to any reason the VBA installation has been removed by Win Creators Update. I do not why and how this happened. After installing VBA again, the Excel object model is again at my disposal. No errors more. Sorry for bothering all of you, have a nice day!
